egestion

While diets may be identical - fish, essentially - the timing of ingestion affects the state of digestion that, in turn, dictates the incidence of egestion.

Mucus losses are also a factor in metabolic faecal loss, i.e., the loss of endogenous matter (including cell debris and protein secretions) that accompanies post-ingestive selection and the egestion of true faeces.

Post-ingestive processes include further particle sorting, digestion, absorption and egestion of true faeces.
